ok....hi everyone....my first post....my question is as follows...so i was hooking up a 600 watt sony amp in my girls car....my prob is this....keep in mind the deck is factory...so i hook everything up....run the remote wire from the ignition switch fuse....everythings works.....so im sittin testing everything...then all of a sudden the amp goes out....so i re-check stuff...to make sure its all hooked up right.....come to find out...its the remote switch wire...why all of a sudden did it go bad?...my power light on the amp turns on for a split second then goes straight to the protect light....why is this?...any and all help is appreciated....thanks....
Welcome! If the amp is going into protect then it sees a problem so it is going into protect. I would say you have your sub wired wrong or you have a blown speaker somewhere. Basically the amp is seeing a load that is unacceptable or a dead short.
thanks for the responses fellas....the ground is fine....as for the speaks bein blown....i unhooked them and still i get the protect light when the amp is turned to the on posistion.....could i have blown something internally?...because when i did turn it on at one point i failed to turn down the radio and upon powering up the music was very very loud...after this instance this is when the amp stopped operating normally....all my fuses and such are ok.....as for the model it is a 4/3 channel sony xplod 600 watt amp...also thanks for the welcome....p
Hey, if you unhook the speakers from the amp and the amp only has power wires to it and it still goes to protect then your amp is toasted.
well....my ground is hooked up....underneath the trunk by where the spare tire is...its grounded off a battery latch that is used to hold the battery in place....it seems legit.....it worked before then all of a sudden stopped...should i maybe sand around the connection to scrap some of the finish offso its pretty much bare metal?....
so where would you suggest?...but will the amp show the protect light evn when not properly grounded?...
not sure...but watch this video http://edesignaudio.com/edv2/ednews/home/blog.php?id=105 basically find a clean spot and san/grind all the metal away. I like using bolts...more secure
That's what the butchers did at the so called professional shop i went to. Man, they caused me so many problems. Nuts and bolts would be much better to ground something and of course sand to bare metal. It's worth a shot stizzi, you wouldn't want to throw away a good amp! Redo the wiring, there may be something you overlooked.
MUST you ground your amp the metal? I didn't know about this part, he said it will give it connection to the battery, but I also seen people run the line to the battery to get connection from the battery.
running a ground back to the battery is the last solution if you cannot find a ground location with a return resistance of less than .5 ohms
again fellas....thanks for the replies....i suppose i will try to re-do the wiring...and find a more suitable spot for the ground...it couldnt hurt to try...right?....and yeah that would suck to throw out a working amp...i will give a shot a let everyone know how things turn out....again i appreciate the help...the stizzi
you could also go to the battery to test the amp.that way you will know 100% if its the ground.if it's a bad ground then you will have to re-wire. just make sure you have enough wire and another set of hands to help.
Wherever you ground....do this test...... Take a volt meter....Put black lead on battery neg....red lead on battery pos. What do you read (car off, accessories off)....You should have 12.6 v...... Then connect black meter lead to the point where you ground your amp...red still on bat pos.....What do you read?? Should be very close within .5 v of your battery voltage..... Lastly connect black lead to bat neg and red lead to ground point for amp... What do you read? It should be zero....If it reads any voltage (especially .5 or more) you have a poor ground....If you have a good ground (zero voltage reading) then connect red lead to power lead at your amp and black lead to ground lead at your amp....What does it read?? It should be very close to battery voltage...if not....you have a bad wire or bad connection on the pos. power wire circuit.....If this all checks out....Leave volt meter hooked this way and turn on ignition and let amp power up....Does voltage stay the same? If so, check voltage at turn on wire.....You should have 12 volts at least here and it should not drop when the amp turns on....If it does...it is bad wire or connection....If all this checks out and you disconnect speaker wires and RCA cables....you have a bad amp.....
